It started with comments on for example "LOCs are constantly in flux?" And that renumbering "consistently failed in the past".

Should I subsititue "transport ID" or |something like that to make it clear that we're not talking about |SIP-like sessions? My understanding re-reading the summary: It depends on the context one have in mind. If a session ID is based on addresses in flux, there are problems and the summary describes just that. One could write down session IDs shall not be based on temporary addresses and we are done. This is not that easy for transport IDs, those have addresses as part of their ID. Add "transport" in the introduction and rename SID to TSID? >> 2. a component of the transport / session identity (TSID) Teco. | |Regards, |Bill Herrin | | |-- |William D. Herrin ................
